FRANKLIN WV. OLIN, OF EAST ALTON, ILLINOIS.

CAN-STOPPER.

SPECIFICATION forming part of Letters Patent N 0. 579,004, dated March16, 1897. Application filed March 5, 1896. Serial No. 581,941. (Nomodel.)

To all whom it may concern;

Be it known that I, FRANKLIN W. OLIN, a citizen of the United States,residing at East Alton, in the county of Madison and State of Illinois,have invented certain new and useful Improvements in Can-Stoppers, ofwhich the following is a full, clear, and exact de scription, referencebeing had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in stoppers for powder-cansand other vessels and it consists in the novel arrangement andcombination of parts more fully set forth in the specification andpointed out in the claims.

In the drawings, Figure 1 is a vertical section of a can and the stoppercarried thereby, and Fig. 2 is a top plan View of the stopper and aportion of the top of the can.

The object of my invention is to construct a stopper or cap forpowder-cans which will effectively close theopening of said can, onewhich is simple in construction and easily secured over the opening orremoved therefrom, one which can be used for an indefinite length oftime without liability of exposing the contents of the can or affectingthe serviceableness of the cap, and one which presents further and otheradvantages to be more fully hereinafter set forth. In detail it may bedescribed as follows:

Referring to the drawings, 1 represents the can, and 2 the top thereof.Stamped from the plate of which the top is composed is aconicaldepression 2, the base of the depression having cut therein anopening 6, aflat annular rim or ledge 7 being left around the opening atthe base of the inclined walls of the conical depression. The ledge 7 isadapted to support the annular basal flange 8 of an outwardly-conicalcap 3, said flange being provided with a series of preferablysemicylindrical openings 5 adjacent the lower edge of the inclined wallsof the cap, the bases of the openings being practically in alinementwith the lips 4, formed or punched integrally with the ledge 7 anddisposed about the in ner or free edge of said ledge.

In fitting the cap over the opening 6 the lips 4:, which are normallybent at right angles to the plane of the ledge 7, of which they form apart, are passed through the semicylindrical openings 5 of the cap, thelatter being thus supported within the depression 2, and the flange 8resting directly on the supporting-ledge 7. The lips 4 are then bent soas to bear against the inclined Walls of the cap, (see Fig. 1,) makingthe cap secure to the can. When the cap is thus secured, a layer ofpaint or similar material 10 is spread between the outer edge of theflange 8 and the meeting edge of the inclined walls of the de pression 2with the ledge 7, the annular ring of paint thus formed making a jointat this point which is air and water tight. By bending the lips 4against the inclined walls of the cap the can and stopper may be used indefinitely, since the lips are not at any time bent sufficiently tocrack or break at their bases.

Having described my invention, what I claim is- 1. In a combined can andstopper therefor, a suitable can cover or end, a depression formed insaid cover, an opening formed in the base of the depression, a ledgesurrounding the opening, a cap adapted to be placed over said openingand having a basal flange adapted to rest on the outer surface of theledge, a series of openings formed in the flange, and lips forming apart of the ledge and adapted to be passed through the openings of theflange and bent in contact with the walls of the cap,substantially asset forth.

2. In a combined can and stopper therefor, a can top or cover, adepression formed in said cover, an opening formed in the base of saiddepression, a ledge surrounding the opening, an outwardly-conical caphaving a periph eral flange at the base'of the conical portion adaptedto rest on the ledge formed about the opening of the depression of thecover, a series of openings formed in the flange adjacent to the loweredge of the conical portion of the cap, a corresponding series of lipsformed along the free edge of the ledge, said lips bein g adapted to bepassed throughthe series of openings and bent against the inclined wallsof the conical portion of the cap, substantially as set forth.

3. In a combined can and stopper therefor, a can top or cover, adepression formed in said cover, an opening formed at the base of saiddepression, a ledge surrounding the opening,

a cap having upwardly-inclined walls, a flange at the base of theinclined walls adapted to rest on the ledge formed about the opening ofthe cover, semicylindrical openings formed in the flange of the cap andlocated adjacent the lower edge of the inclined walls of the cap, aseries of lips corresponding in number to the said openings and formedalong the free edge of the ledge and integral therewith, said lips beingadapted to be passed through the series of openings and their projectingends deflected or bent into contact with the inclined walls of the cap,and a suitable Water-tight layer of paint or similar material adapted tobe interposed between the outer edge of the flange of the cap and theadjacent walls of
